What is wrong with my code?

Could you check what is wrong with my code? All of the second question answers says that you guessed the correct answer.

Here is my code:

var correctGuess = false var randomNumber = Math.floor(Math.random() * 6 ) +1; var guess = prompt("Im thinking of a number between 1 and 6"); if (parseInt(guess) === randomNumber ){ correctGuess = true; } else if ( parseInt(guess) < randomNumber ) { var guessMore = prompt('Try again. The number I am think of is moer than ' + guess); if (parseInt(guessMore) === randomNumber) { correctGuess = true; } } else if ( parseInt(guess) > randomNumber ) { var guessLess = prompt('Try again. brah. The number is actually lower than' + guess); if (parseInt(guessLess) === randomNumber ){ correctGuess = true; } } if (correctGuess = true) { document.write('You guessed the number!');

} else { document.write('Sorry. The number was ' + randomNumber); }

Your final test contains an assignment instead of a comparison:

if (correctGuess = true) {

So instead of testing if correctGuess is true, it makes it true. So the 2nd try will always seem to be right.

Also, when testing a boolean value, you don't even need a comparison expression, just name the term:

if (correctGuess) {
